Please help - App State Image Path cannot point to images in Local Assets??

So I'm making an offline memory game with a bunch of images that I feed into an App State. To get it to work initially I had to feed my App State with web URL's thinking I could definitely change it back later when I got to testing in local run but I still get [object Event] if I put in assets/images/image01.jpg instead of https://storage.googleapis.com/flutterflow-io-6f20.appspot.com/projects/(...)/image01.jpgSo how can I point this to an image stored in local assets?? I'm out of ideas here. Really need the app to work offline.
